Just get up early every day and walk for two hours after breakfast. If you are old and young, you can walk for two hours every morning. Believe me, your stomach will see obvious effects in two weeks. Congratulations, you have lost weight successfully. This is the healthiest and most effective method. Trust me, you can do it! There is also what others say about doing sit-ups, and you should stick to it every day. If you don't want to do it one day, it will rebound quickly. Doing sit-ups is really not as obvious as walking for 2 hours every morning as I said. Although thin belly said that sit-ups are also thin, 1 insist on 2 being thin and 3 rebounding quickly. Sit-ups are only an auxiliary means to lose weight. If you have a chance to come to Nanyang Yangfei Fitness Club, I can be your coach. My last name is Gao, thank you.
